Don't try to monetize every hobby
I think it's important to separate fun things from business ideas. Sometimes a hobby can turn into a business but not every single hobby you pick up should be an effort to squeeze cash from the hours spent in it.
You should be able to have fun with what you like to do without worrying about follower counts or subscribers or sponsors. It's important to be able to spend what free time you might have in the week on things that make you happy, not things that cause you stress.
Imagine getting a new bike. You ride it on your days off. It's fun. Now imagine strapping go-pros to the bike and making YouTube videos about bike parts. Suddenly the fun thing on the weekend becomes job #2 or job #3.
You are allowed to have fun.
